Introducing the AOC-6843 series: our cutting-edge cage guide control valve renowned for its large Cv value and unparalleled dynamic stability. Engineered for a diverse range of heavy-duty applications, this series boasts a pressure-balanced trim, expertly designed for handling high-pressure drops with ease. The AOC-6843L//D/E variants elevate performance by integrating multi-hole type cages, specifically crafted to meet stringent low noise and anti-cavitation standards, surpassing conventional cages used in standard models. Notably, all elements, except for the innovative multi-hole cage, are fully interchangeable with components from the AOC-6843 series, ensuring seamless integration and adaptability. For the most demanding fluid conditions beyond the scope of this series, we recommend opting for the SNT LIMIPHON control type, a sophisticated choice for exceptional fluid control.
